Query: G.N.I.S.

Hurtado & Gallen (2025) ... explored the hypothesis that deglaciation of the northern Sangre de Cristo Mountains (SCM) affected spatial and temporal slip patterns on the range-front normal fault ... two distinct events at Major Creek at ca. 13–8 ka and ca. 8 ka, and three events at Carr Gulch at ca. 27.5–22.5 ka, ca. 20 ka, and ca. 8 ka ... Fault mapping shows a composite fault system with a relatively simple large-scale geometry (Figs. 1C and 3C), with one exception: a series of faults, known as the “Villa Grove Swarm” between Carr Gulch and Major Creek, which strike NW away from the main fault trace at a relay zone ... results suggest that deglaciation of the SCM unclamped the Sangre de Cristo fault and affected spatial and temporal slip patterns. Long-term tectonic extension dominates spatial and temporal slip patterns, but our results support the notion that climate, via glacial advance and retreat, can affect fault-slip variability, implying that earthquakes can be clustered in space and time.
